To all whom it may concem: i

' Be .it known that I, RICHARD KnNN'nnY a citizen of the United States, residing at Chicago, in the county of Gamma State of Illinois, have invented a certain new and useful Improvement" in Carbureters, of which the following is av specificationk I My invention relates to improvements in carburetors, and is illustrli ted in one form] in the accompanying drawing, which' shows a section through my device. {if

The cylindrical casing Ainclosing the annular air passageway A hasatone-end the enlargement A which-incloses the carbureting chamber A in communication with the engine by means of the mixture discharge passage A. The conical partition A? perforated at A and carrying the screwthreaded hub A, separates the airpassageway A? from the carbureting chamber A The cylinder B which is screw-threaded upon the hub A is located centrally within a the air passage A and contains sl idably mounted therein the hollow, druini B I 5 mounted upon the hollow piston rod or tube; 23 which'is in tur'n's'lidably mounted within; the hub AT. The interiorof the drum B? communicates at one sidefivith the interior of the tube B and is provided at the other with the passageway Btcontrolled bya valve B and spring *B 'i The passageway Ein the Wall of the tube B furnishes coin munication between said, tube: and the yinterior of the cylinder B above the-.dru

The spring B is inclosedwithin the .der B, surrounds thetube B and pressed between the surface of the hub A and'the drum B. y p The cylitider B is closed at. one end b the'fixed drum C which is providedtw v the passageway in opposition to the pasfl, sageway 13* in the drum B and wit lrilthe passageway C vthichmay be adjusted by, means of the needle valve C and which is controlled by the valve C and spring The turn cock C screw;threaded to theiend of the cylinder B communicates W'ltl, the fuel supply by means of the tube C7. "The tube B which projects upwardly intbthe chamber A carries the hub D from which projects the conical plate D? parallel with and adapted torest upon the partition A and having the triangular openin s D about its center, and carrying the Wire gauze' 5 partition D through which projects the end the tube B Specificatilin of Letters Patent.

is slidably mounted upon the collar F and is; provided'with the openings F in oppo sf'tion to the openings F and the operatlng link F. i l It will be evident that while I have shown in my drawing an operative device still fmany changes might be made in the size, ,ishape and arrangement of parts without de- 1 parting materially from the spirit of my i-n vention, and I wish, therefore, that my from the cylinder A with the air passage A The annular collar F drawing be regarded as in a sense diagrammatic. I I a o The use and operation of my invention-are as follows :\Vhen the engineds at stand still and no demand is made upon the can bureter, the conical disk within the car-- bursting chamber rests upon a corresponding conical wall ofsaid chamber and the drum or piston attached to the tube carried by the conical disk is in its lower position,

the fuel having passed upwardly to filllthe carbureter above the piston. It now, the engine is started the suction will draw air through the air passage lifting the conical disk. The piston will then rise with the disk and the fuel being compressed by the J vlierli ittu ill be-atomized and carried into the-"cylinder of the engine. Any fuel which is notcarried away by the first stroke will 1 be arrested and caught upon the wire gauze Where it willfbe taken up by the air atgithe next stroke. The amount of air passing through the carburetor may be adjustedby means of thevalve at the opening to /the chamber, and this valve whichvopera te s to vary the amount of air, also operates to i piston willcbe squirted out at the top of the fplston rod into the carbureting chamber",

vary the amount of fuel fed to the engine, in

view of the fact that the amount of fuel dependsupon the length of travel of the conical plate and the piston, and the travel of the piston and plate depcnds'on the amount of air which is drawn through against the nlate. The richness of the mixture'is adjustedby means of the auxiliary air intakes leading to the carbureting chamber; above the conical valve plate.

l A carburetor comprising a cylindrical air passage, :1 carbureting chambei', separated therefrom by a perforate conical wall, a cylindrical oil. chamber concentric with 3 said air passage, a conical valve plate in said carbureting chamber.

carbureting chamber, perforations :therethrough, a pistonin said 011 chamber and a.

piston rod connectin said piston and valve 'through, a piston in said oil chamber and a piston rod connecting said piston and valve plate, a passage through said piston rod and a check valve in said piston.

A carburetor comprising an air passage, a carburcting chamber, separated therefrom by a perforate wall, an oil chainher within said air passage, a perforate valve plate in said carburetiiig chamber, a

piston in saidoil chamber and a hollow piston rod connecting said piston and valve plate, a check valve in said piston.

4. A carburetor comprising an air passage, therefrom by a perforate wall,aii oil chamber within said airpassage, a perforate valve plate in said carbureting chamber, a piston in said oil'chamber and a hollow piston rod connecting said piston and valve plate, a

check valve in said piston, means for (301k a carburet-ing chambe', separated trolling the supply of ,oil to said chamber,

means for controlling said air passage; and

an auxiliary adjustable air supply to said carbureting chamber.

5. A carbureter coii'iprising a cylindrical air passage, a carb'ureting chamber, separated therefrom by a perforate eonical Wall, a cylindrical oil chamber concentric with said air passage, a conical valve plate in said carburetiiig chamber in opposition to said perforate wall, perforations there through, a pistoniii said oil chamber and a piston rod connecting said piston and valve plate, a passage through said piston rod and a checkvalve in said piston.

ti. A- carburetor comprising an air passage, a carbureting chamber, separated therefrom .by a perforate wall, an oil chamber within said air passage, a perforate valve plate in saidcarbureting chamber in opposition to said perforate wall, a piston in said oil chamber and-a hollow piston rod connecting said piston and valvc'plate, a check valve in said piston.

7. A carburetor comprising a carbureting chamber, a perforate disk slidably mounted upon the walls thereof, a tubular piston rod carried by said diskand' pumping means carried by said piston rod, means fore-losing and unclosing the perforations in said disk. I v

8. A carburetor comprising a carlmreting chamber, a perforate diskslidably mounted upon'the walls thereof, a tubular piston rod carried" by said disk and pumping means carried by said piston rod, means for closing! and unclosing the perforations in said disk, said means comprising a fixed wall ii oppo sition to said disk.
